Presentation 1 : Oral
The type Ia supernova rate at a redshift of 0.1
G. Blanc, the EROS collaboration
At the present time, there are few well studied supernovae and systematic searches are necessary. It happens that the rate measurement is an interesting by-product of such systematic supernova search programs (basically made for cosmological purposes). In the beginning of 1999 the Supernova Cosmology Project coordinated a worldwide nearby ($z \sim 0.01 - 0.2$) type Ia supernova search, and provided spectroscopic and photometric follow-up. The EROS experiment was involved as a search facility and discovered almost half of the whole sample obtained. The type Ia supernova rate has been derived from this search, at a mean redshift of 0.1.
